Application filed. January 19, 1914. Serial No. 813,024.

To all wlw/nt it may concern Be it known that QUINT G. EDDiNs, a citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Sash-Holders, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to sash holders of the spring type, in which the spring is located at some point or points between the window frame and the sash frame and either presses against one of the sashes, or presses the sashes or portions thereof toward each other, whereby there is sufficient friction between the parts to maintain the sash in any adjusted position.

Stated in terms of its specic embodiment which will be hereinafter described, my in vention comprises a flat metal strip or spring located between parts which move upon each other, as for example the sash and the frame; this spring having a length greater than the length of the moving part which passes over it, and being secured at its opposite ends to points on a relatively fixed part, the distance between which is less than the length of the spring. With this construction a bulge must always exist at some part of the length of the spring, so as to produce suliicient friction to hold the movable member or sash in any desired position.

1n the accompanying drawings I show the best form of my invention now known to me, but l desire to have it understood that the invention may be given many forms by those skilled in the art, without departing in any way from its generic principle.

Of the drawings, Figure 1 is a vertical transverse section of a window frame showing upper and lower sashes in closed positions, Fig. 2 is a similar section showing the lower sash raised, and the upper sash lowered, and Fig. 3 is a plan view of the spring strip constituting the sash holder proper.

Referring to Figs. 1 and 2, the window frame is designated 10, the usual parting beading by 11, and the inner and outer sash stops 12 and 13. Between the inner sash stop 12 and the parting beading 11 is positioned the lower sash, while between the parting beading 11 and the outer sash stop 13 is positioned the outer sash 15. rThe relative positions of the sash stops and the parting beading are made such, that the sashes 14 and.15 under all conditions have ample freedom of movement up and down. Under such conditions, there is not sufficient swelling under change of weather conditions, or slight warping of the stops, beading, or sash frames, to bind the sashes. interpolated between the sash stops 12 anc 13 respectively and the sashes 11 and 15, are the sash holders 16 of my invention. in this embodiment they are secured to the inner edges of the sash stops at points 17 and 18 spaced apart a distance less than the extended length of the strip between them, whereby, that portion of the strips 16 adjacent the sash being pressed flatly against the edge of the sash stop, there is'when the sashes are in the position of F ig. 1, a bulged portion above and below the lower and upper sashes 1-l and 15 respectively. l

The strips 16 are preferably of smooth tempered steel, such as clock spring steel, but they may be made of bronze, brass or any other material, smoothly finished to the requisite degree, the smoothness of the finishing being varied to produce greater er less amount of friction if desired. Each sash is strongly pressed, by the bulged portion of strip 16 against the parting beading, thus forming a weather-proof joint between the sash and the beading in each case. rlhis joint is suliiciently tight not only to prevent the entrance of dust and dirt under fair weather conditions, but to prevent the entrance of moisture and water during the stormiest of weather. vWhen the sashes are moved, the bulge of the strip 16 at the one end disappears, and another bulge appears at the opposite end, the strip during the raising or lowering of the sash, as the case may be, sliding past the face of the sash frame. 1n other words, the flattening out of the bulge at one end of the strip by the movement of the sash, gives rise to a longitudinal movement of the body of the strip with respect to the sash stop or other fixed part to which it is secured. The smoothness of the spring strip 16 should be suflicient to permit this to take place easily. rlherefore when the sashes are moved from their normal positions, to positions such as shown in Fig. 2, the sash is pressed flatly against the parting beading by bulged portions both above and below it, and the bulged portions retain the sashes in their adjusted positions, the weight of the sash being insufficient to eliminate the bulged portion on the under made from a spring strip of veryV small' width, and very light weight, such vas the ordinary clock spring strip. Obviously by simply increasing the size and Weight of the strip, the sash holder may be made suitable for retaining in position sashes of any desired size whatsoever.

VAs above pointed out, the holding power of the bulged portions of the strip .depends primarily up on ,the resistance to longitudinal movement of the strip with respect to the sash stop or other fixed part to which it is secured, and this movement may not only be variedl by Y varying the smoothness of the strip itself, kbut the smoothness of the adjoining faces of the sash holder and sash stop, as well as the closeness of the space between the sash and the sash stop may likewise be adjusted to vary this holding power. Attention need be paid to these matters however principally in sash holders of the very largest sizes. Y

` to hold theV same.

a beveled portion thereof as in many well known forms of the spring type `of sash holder. f

l/Vhat I claim kis:L The combinationl of a frame, ay sash slid-A 30 bear directly upon the edges of the sash 0r ing therein, and a spring between the sash and frame, 'having its ends secured to points on the frame spaced apart av distance less than the length of the spring, whereby a portion of said spring will form a projecting bow above or below the bearing surface of the sash, or both, according to. the direction of movement and position of the sash,

In testimony whereof I aliiX my signature n 1n presence of two witnesses.
